Since I have two defective pairs of KZ ZS3 lying with me (right side silent in both), I wanted to know whether I can take out the drivers & everything from the left side shell and put them in the right side shell and have at least one working pair? Will it even work properly? Thanks!
Definitely would work well. I'd just want to make sure to don't put much stress to remove the driver, otherwise, it can damage the driver too. Since you're gonna open it I'd recommend you to replace the stock heat-shrink tubing to a PVC tube normally used for CIEMs. Maybe @CoiL can help you since he has reported about how crap is the construction of the stock tube, lol.
